Exchange 2003 not downloading email to Outlook 2010 Inboxes

Exchange 2003 not downloading email to Outlook 2010 Inboxes

Environment:
Windows Server 2003
Exchange Server 2003
Clients – Windows 7 Professional
No software updates.
No software installs.
No hardware installs.
Email sent outside the domain (Internet) is sent and received successfully.
Email sent internally inside the domain is sent to Exchange, and retained in Exchange, but not retrieved by the internal recipients.
All of the “missing” email is visible in OWA, which proves it is held in Exchange, but the Clients cannot see/retrieve it.

History:
This installation has been working without a hiccup for years.

Corrective action taken:
Rebooted all Workstations.
Rebooted Server.

Problem outline:
Exchange OWA shows all Inbox email so the email is inside the Exchange Server.
At the same time, Outlook displays all “old” email, but does not display current email.

Final plea:
I’ve been doing MS since DOS, 1982, but this one has me stumped. I have never posted a problem to Experts Exchange. Maybe this one will be worth all the Member Dues I have paid for many years. It only takes one to be worth it all.
